BAG-FEEDER.

Specification of Letters Patent.

Application filed October 559, 1M5. Serial No. 58,567.

-5 and useful. Improvements in Bag-Feeders;

and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and The primary object of thisinvention is to provide simple and highly ellieient means for separatingthe topmost bag or bag-tube from a pile or stack thereof, preparatory tofeeding it to a printing-press or other long handling machine.

According to my invention restraining pressure is applied at or near onelongitudinal side of the pile, on the top thereof, and

perferahly near one corner, and by introducing a separating elementbetween the upper and, lower portions of the top-most bag-tuliie, theother longitudinal edge of the latter, at the opposite side of the pile,will be drawn inwardly a sufficient distance to clear a hold-downelement, whereupon as the separating element is withdrawn the raised orseparated edge of the bagtube will be prevented from returning to thepile.

The separated bag-tube may then be fed from the pile, 4

Fig. 4 is' a view similar to Fig. 3 but withthe separator withdrawn and the feeding means 40 in position to engagethe edge of the bagtube.

Referring to the drawings, 1 designates a stack or pile of bag-tubeswhich may be maintained at practically a -constant level.

by any suitable or known means. The longitudinal axis is perferably atright angles to the fowl-path to a. printing press or other hag-handlingmachine. The top of the pile is engaged by a presser 2 which is designedto bear against the,topniost hag-tube at a.

point near one edge of the pile, and prefen ably-in close proximity toone of the corners. The pressure exerted must be sutlicient to preventany bodily'displacement of. the

topmost hag while such presser naintains a nxed 16l&l23.011 to the pile.I also provide an additional hold-down 3, for engagingthe opposite edgeof the pile. This hold-down,

pile provided. it exerts less friction thereon ()ne hold-dow11 3 willthan the presser 2 suiiice but more may he used. I

designates a reciprocating separating member which is designed to enterbetween the two sides, or upper and lower portions, of the topmostbag-tube, and by moving inwardly a suiiieient distance separate theupper and lower portions of the bag-tube to suoh an extent as to drawthe one edge thereoi. upwardly and forwardly from beneath the hold-down.3. This withdrawal of the edge of the bag-tube is rendered possi: bleonly by maintaining pressure on the top of the pile through the mediumof presser :2.

In the form illustrated, while the edge of Patented July 25, 1916,

come together it will fall against and rest upon the holddown 3. In thisway the edge of the topmost bag-tube is held suiiiciently above the topoi the pile or stack to enable the bag to be engaged by suitable means,such as indicated at 6, and removed from the pile. In the form shownthis is facilitated. by moving presser 2 from engagement with the pile.By the time the bag is we moved from the pile the presser is again movedinto engagement with the pile so as to exert the necessary pressurethereonloefore the separating element 5 acts on the next bagg tuhe to asufficient extent to draw the edge thereof inwardly and forwardly e'toredescribed. 7 Any suitable means may he employed for manipulating thevarious parts, that is to say, fori'aising and lowering the presser andhold-downs; for reciprocating the separating'elen'irnt; and for removingthe topmost or separated bag-tube irointhe pile.

The advantages of my invention will readily heappreciatedbythose' skilin the art, and it will be observed that by means thereof I am enabledto easily and positively insure the separation of the topmost bag from astack thereof.

1 do not restrict myself: to any particular construction for carryingout this invention, since it is manifest that any suitable means may beemployed for applying suiiieient pressure against the top of the pile toinsure the withdrawal of one edge of the topmost bagtube from its normalposition and for pre venting it from returning to its former po sitionafter the separating means has been withdrawn. 13y top of the pile ismeant that portion of the pile adjacent the separating means, andtopmost hag-tube refers to that hag which is directly in position to heacted upon by the separating means.

I claim as my invention:

1. In a hag-tube feedeiy'means for apply ing pressure against the top ofa pile of bagtubes near one side thereof, means for separating the twosides of the topmost hagtube while pressure is applied thereto by thefirst mentioned means, such separating means serving to raise and drawinwardly one longitudinal edge of the topmost bagtube, and means i'orremoving said bag-tube from the pile.

2. In a hag-tuhe feeder, means for applying pressure against the top ofa pile of hagtuhes near one side thereof, means for separating the twosides of the topmost bag-tube while pressure is applied thereto by thefirst mentioned means, such separating means serving to raise and drawinwardly one longitudinal edge of the topmost bag-tube, and feedingmeans for engaging said longitudinal edge.

In a bag-tube feeder, means for applying pressure against the top of apile of hagtuhes near one side thereof, means for entering between theupper and lower sides of the topmost hag-tube while pressure is ap'plied thereto by the first mentioned means, a hold-down member forengaging the pile,

and means for engaging and feeding such topmost hag-tulle from the pile.

4,. In a hag-tube feeder, means for applying pressure against the top ofa pile of bagtubes near one side thereof, means for entering between theupper and lower sides of i the topmost bag-tuhe while pressure is upplied thereto by the first mentioned means, a hold-down member forengaging the pile near the other side thereof and upon which the topmostbag-tube is designed to rest, and means for engaging and feeding suchtopmost hag-tuhe from the pile.

In a hag-tube feeder, means for applying pressure on the top of a pileof bag-tubes near one of its Corners, means for entering between the twosides of the topmost bagtuhe and drawing one side edge toward the sideupon which such pressure is applied, hohhdown means engaging such pilewhen such topmost bag-tube is moved by said entering means, and meansfor feeding the topmost hag-tube from the pile.

\5. In abag tuhe feeder, a presser member for engaging the top of a pileof bag-tubes near one side thereof, means for separating the upper andlower portions of the topmost hag-tuhe while the latter is engaged bysaid presser member for drawing the 1011- gitudinal ,edge of saidtopmost bag-tube away from the other side of the pile, a, holddownmember for engaging the pile when said topmost hag-tube is drawn awayfrom said side and upon which said hag-tube is designed to rest whensaid separating memher is withdrawn, and means for engaging and feedingsuch topmost bag-tube from the pile. I

in testimony whereof, I have signed this speeifieatimi in the presenceof two subscribing witnesses.
